Thanks. The implementation of the reflections ist not finished, they might even be improved. However, as they are "fake" reflections it's impossible that they ever will look like the hardware-supported reflections as seen in current game engines. Still, for the fact it's just a fake I'd say it looks pretty well.

Ah, well, yes. I have no means to distinguish between different "materials" on the floor as long as X-Ray treats them as the same material (what's the case here). However they should be less reflective because color plays a role as well.

Interesting effect. I'm not sure it looks right in that particular building as the roof is in tact so theres no way rain could blanket the whole floor in that building, but the effect does look pretty good.
